Cutaneous rejuvenating and healing product, method for its manufacture and uses thereof

Abstract

Cutaneous rejuvenating and healing product comprising ground material made up of the mother of pearl testa of a bivalved mollusc and the cell dilacerate of the mollusc mantle. After being enzymatically and thermally treated, both phases are blended to a gel or cream, before being combined with excipients such as menthol, camphor, benzoin, citric acid, methyl oxibenzoate, cetylic alcohol, stearylic alcohol, officinal vaseline, glycerine, purified water, algae extract, calcium hydroxide and copra extract. The product of the invention is for dermatological and cosmetic use.

We claim: 
     
       1. A cutaneous healing composition comprising an effective amount of a product obtained by the process comprising: a) subjecting cells from the mantle of the bivalved mollusc Pinctada maxima to a thermal treatment in a vacuum;   b) freeze-drying said thermally-treated cells;   c) mechanically grinding the pearl testa of the bivalved mollusc Pinctada maxima;   d) subjecting the mechanically ground pearl testa to an ultrasound treatment and then to an enzymatic treatment; and   e) mixing the material obtained in step b) with the material obtained in step d).   
     
     
       2. The composition of claim 1 wherein the material obtained in step d) is subjected to a chemical acid treatment for enzyme deactivation prior to step e). 
     
     
       3. The composition of claim 1 wherein the material obtained in step d) is subjected to an evaporation treatment at 50° C. prior to step e). 
     
     
       4. The composition of claim 1 wherein the material obtained in step a) is filtered on a diaphragm and concentrated by centrifugation prior to step b). 
     
     
       5. The composition of claim 1 wherein the product is in the form of a gel, cream or solution. 
     
     
       6. A composition comprising the product of claim 1 blended with a vehicle selected from the group consisting of menthol, camphor, benzoin, citric acid, methyl oxibenzoate, stearyl alcohol, officinal vaseline, glycerine, purified water, vitamin A, algae extract, calcium hydroxide and copra extract. 
     
     
       7. A dermatological composition comprising an effective amount of the product of claim 1. 
     
     
       8. A cosmetic composition comprising an effective amount of the product of claim 1. 
     
     
       9. The composition of claim 1 wherein carbonic anhydrase or trypsin is used in the enzymatic treatment of step d). 
     
     
       10. A composition comprising the product of claim 1 blended with a vehicle that accentuates the healing effects of the product and promotes the penetration of the product into the skin. 
     
     
       11. A method of preparing a cutaneous healing composition comprising the steps of: a) subjecting cells from the mantle of the bivalved mollusc Pinctada maxima to a thermal treatment in a vacuum;   a) freeze-drying said thermally-treated cells;   c) mechanically grinding the pearl testa of the bivalved mollusc Pinctada maxima;   d) subjecting the mechanically ground pearl testa to an ultrasound treatment and then to an enzymatic treatment; and   e) mixing the material obtained in step b) with the material obtained in step d).   
     
     
       12. The method of claim 11 further comprising the step of subjecting the material obtained in step d) to a chemical acid treatment for enzyme deactivation prior to step e). 
     
     
       13. The method of claim 11 further comprising subjecting the material obtained in step d) to an evaporation treatment at 50° C. prior to step e). 
     
     
       14. The method of claim 11 further comprising subjecting the material obtained in step a) to filtration on a diaphragm and concentration by centrifugation prior to step e). 
     
     
       15. The method of claim 11 further comprising the step of formulating the composition in the form of a gel, cream or solution. 
     
     
       16. The method of claim 11 wherein carbonic anhydrase or trypsin is used in the enzymatic treatment of step d).
